程序里的注释是很重要的。它们可以用自然语言告诉你某段代码的功能是什么。在你想要临时移除一段代码时,你还可以用注解的方式将这段代码临时禁用。接下来的练习将让你学会注释:
1 2 3 4 5 6 7 8 9 | # A comment, this is so you can read your program later.
# Anything after the # is ignored by python.
print "I could have code like this." # and the comment after is ignored
# You can also use a comment to "disable" or comment out a piece of code:
# print "This won't run."
print "This will run."

$ python ex2.py
I could have code like this.
This will run.
